Principle of work of the present invention:
(1) braking function: function handle is placed in " commonly using " position, clockwise direction rotation hand wheel, drive the key wheel in imput shaft to rotate, transfer torque on miniature gears by power-transfer clutch, miniature gears drives bull gear drive, realizes braking function.
(2) rapid recovery function: under braking mode, anticlockwise direction rotation hand wheel about 20 ~ 60 °, drive power-transfer clutch axial motion, the transmission of imput shaft to miniature gears disconnects by power-transfer clutch, realizes rapid recovery function.Anticlockwise direction can only rotate 20 ~ 60 °, and the situation therefore not having handwheel transfer during rapid recovery occurs.
(3) force adjustment function: function handle is placed in " force adjustment " position, now the sour jujube tongue of hand brake inside is inoperative, clockwise direction rotation hand wheel, the key wheel in imput shaft is driven to rotate, transfer torque on miniature gears by power-transfer clutch, miniature gears drives bull gear drive, can realize braking.As required, can reduce braking force by rotating counterclockwise of handwheel, rotating clockwise handwheel can increase braking force, thus realizes force adjustment function.
Before improvement, under gravity, during hand brake complete incidence graph state, chain will be in location status as shown in Figure 10.After improvement, by arranging inhibiting device at big gear wheel rear, during hand brake complete incidence graph, chain is in location status as shown in figure 11.Under complete incidence graph state, after hand brake chain improves, offset by 47mm to the right than improvement.
Braking procedure: during initial release position, chain is positioned at the position shown in Figure 11.Now, one end of torsion spring is limited in bumping post I place, and the other end is limited in bumping post III place, and the guide plate be connected with bumping post I is limited in bumping post II place.When implementing braking, handwheel clickwise, drives key wheel to rotate by imput shaft, and then drives miniature gears to rotate clockwise by power-transfer clutch.Miniature gears engages with big gear wheel, thus drives big gear wheel anticlockwise direction to rotate.Because bumping post III is fixedly installed in big gear wheel, therefore, bumping post III rotates with the rotation of big gear wheel, and now torsion spring is motionless.After big gear wheel is revolved and turned around, the termination of one end is blocked by bumping post III, now torsion spring under the drive of bumping post III with big gear wheel left-hand revolution.After big gear wheel continues to rotate a circle, the termination of the torsion spring other end is blocked by bumping post I, and now big gear wheel amounts to rotation two weeks (the chain amount of being involved in is about 500mm).Because bumping post I is fixedly installed on guide plate, therefore, along with the continuation of big gear wheel rotates, torsion spring drives guide plate 4 left-hand revolution by driving bumping post I.Now, be fixed on the bumping post II on base plate and guide plate 4 relative motion, thus in the groove of guide plate 4 clickwise.After bumping post II rotates at most 3/4ths circles as shown in Figure 7 in the groove of guide plate 4, guide plate 4 is blocked by bumping post II.Now continue to rotate, torsion spring will produce torsion and hinder braking to implement again.
As mentioned above, when the hand brake in the application implements braking, inhibiting device can ensure that big gear wheel rotates in two and 3/4ths circles (amount of being involved in can reach more than 800mm), and torsion spring does not produce reverse inhibition.And the at present conventional maximum amount of being involved in of hand brake design is only 458mm, therefore the design of this position limiting structure meets hand brake completely and brakes operating needs normally.
Alleviation process: under braking mode, anticlockwise direction rotation hand wheel about 20 ~ 60 °, drive power-transfer clutch axial motion, the transmission of imput shaft to miniature gears disconnects by power-transfer clutch.Anticlockwise direction can only rotate 20 ~ 60 °, and the situation therefore not having handwheel transfer during rapid recovery occurs.Chain moves after being subject to gravity, and it rotates relative to imput shaft by the large gear turn the small gear, and then realizes alleviating operation.During alleviation, along with the clickwise of big gear wheel, bumping post III rotates with the rotation of big gear wheel, and now torsion spring is motionless.After big gear wheel is revolved and is turned around, the termination of one end by bumping post III clamping, now torsion spring under the drive of bumping post III with big gear wheel left-hand revolution.After big gear wheel continues to rotate a circle, the termination of the torsion spring other end is by bumping post I clamping, and now big gear wheel amounts to rotation two weeks (chain discharging amount is about 500mm).Because bumping post I is fixedly installed on guide plate, therefore, along with the continuation of big gear wheel rotates, torsion spring drives guide plate 4 clickwise by driving bumping post I.Now, be fixed on the bumping post II on base plate and guide plate 4 relative motion, thus in the groove of guide plate 4 left-hand revolution.Bumping post II is after the groove inward turning of guide plate 4 goes to groove ends, and guide plate 4 is blocked by bumping post II.Thus achieve the rivet of fixing chain and chain-rolling axis in the same horizontal line, avoid chain and naturally droop based on Action of Gravity Field, cause chain center and chain-rolling axis center there is no lateral excursion distance.
Beneficial effect of the present invention:
(1) imput shaft of the hand brake described in the application and the width between centers of chain-rolling axis end chain increase 47mm, after hand brake entrucking, ensureing under the prerequisite that handwheel is not interfered with passenger vehicle windscreen, under chain-rolling axis end chain center and car, fixed pulley end chain central cross offsets and is reduced to 53mm, when not only avoiding hand brake braking, chain and movable pulley are interfered and affect the in-use performance of hand brake, and visual effect is also better simultaneously.
(2) connection between hand brake end axle and imput shaft adopts elastic cylinder finger setting, compared with the welding manner of existing hand brake, is more conducive to the maintenance that imput shaft composition decomposes.
(3) hand brake after improvement after suitable its mount pad position of adjustment (avoiding interfering with passenger vehicle windscreen), still can ensure the in-use performance of lorry hand brake system, and before hand brake improves rear and improvement, multiplying power is consistent.
